copied!<ol> <li>Forget about the UI. </li> <li>Represent each object in its base form --only put object properties in it. Example, a car will have a size and ability to move. But it won't have the logic to make it move. Similarly a traffic light will have states such as green, amber and red. But it won't have the logic to switch between these states. Similar classes for roads, lanes etc.</li> <li>Build a different class for the driver. This class will contain all methods such as lane shifting, stopping, turning, moving forward etc. More technically, this will be your "actor" and will act on the veichle. A similar actor would be for traffic light control which will act on a network of traffic lights. Make it an interface and have two implementations to it --one that takes advantage of interconnectedness and other that operates on static times. </li> <li><em>Optional</em> add a UI on top of this object model. Don't go fancy, have simple dots to begin with. Once you get all simple stuff working, adding more fancy features should be easy and impact free (relatively). </li> </ol> <p>This will be a very challenging project. </p> <p>But if your objective is a proof of concept, I have a simpler suggestion. You can go user generated here and get all the complexity of simulation out and all the accuracy in. Start with 15-20 remote controlled cars, a cardboard model of a fictional town, some bulbs to simulate traffic lights and some volunteers who know how to drive. Have a preprogrammed sequence of on and offs written on paper and assign some of the volunteers to control those lights. Have another set of volunteers control the cars. If you have hands on experience in basic electronics you can build a timer controlled circuit to control the lights. </p> <p>All the very best!</p>
